The third canoe, with six teenagers and a coach in his 50s, was unable to get upright. A rescue helicopter extracted five of the teens, with one managing to swim to shore. A bystander boat picked up the coach.
Emergency medical personnel evaluated two adults and six teens, and all refused EMS transport.
